Spacers

Vertical spacing in HTML emails can be tricky, because of inconsistent support for margin, padding, and <br> tags. Here's how to create simple yet reliable spacers for your emails, using basic HTML and Tailwind.


The Div

This is the simplest kind of spacer you can use in an HTML email.

Being a <div>, it can be used anywhere such an element is allowed. In our case: before/after a <table>, inside <td> or <th>, or inside other <div> elements.

<div class="leading-64 sm-h-32">&zwnj;</div>

Here's the idea:

  1. leading-64 adds line-height: 64px; - this is the default height, for desktop clients
  2. sm-h-32 sets height: 32px; for the sm breakpoint - this is the responsive height
  3. We use a &zwnj; to add something inside, so it can take up height reliably in all email clients

Custom top/bottom heights

In case the sm-h-{$size} classes you have defined in your (custom?) Tailwind config are not enough, you can double up by using padding instead:

<div class="leading-64 sm-h-0 sm-py-64">&zwnj;</div>

sm-h-0 will reset the height to zero on the sm breakpoint, and sm-py-64 will add 128px of total padding,

The Row

Use this one directly inside a <table>:

<tr>
  <td class="h-64 sm-h-32"></td>
</tr>

By default, Maizzle will transform the inline CSS height: 64px; to a height="64" attribute, for consistent email client support.

The Table

A simple table with an empty cell that has a height set. Use it anywhere you can't use a Div or Row spacer.

<table class="w-full" cellpadding="0" cellspacing="0" role="presentation">
  <tr>
    <td class="h-64 sm-h-32"></td>
  </tr>
